What are tectonic plates and how do they help us? When tectonic plates collide together it can cause volcanoes to erupt. New Zealand is on the active boundary of Australia and Pacific Plates. About 14,000 earthquakes happen in and around New Zealand every year. Tectonic plates started 25 million years ago. When tectonic plates collide they push magma up which causes volcanoes to erupt. Most Tectonic plates go apart, beneath the sea. The earths crust is like a cracked shell of a boiled egg. Tectonic plates can help us when they collide together and make volcanoes erupt because they can make islands bigger. Tectonic plates are made of slabs of rock that stick together they are big brown-grey things that move. We don;t think they are moving but they slowly are. New Zealand is on two big tectonic plates. Tectonic plates are a mix of continental & oceanic crust. Tectonic plates move in different ways one goes one way and the other way. There are seven main tectonic plates.
